Pros: Can disparate a great amount of heat
Special care: Use thermal compound between the chip and the heat sink. Be
careful installing the heat sink, to avoid a cracked chip.

Water Coolers
Pros: Can disparate a great amount of heat, low noise
Special care: Use thermal compound between the chip and the water jacket.
Be careful installing the heat sink, to avoid a cracked chip. A large pump
should be used to move as much water though as possible. Use only distilled
water with anti-freeze to reduce the amount of mineral build up.
Questions?
I normally use a good HSF to keep my CPUs cool.

Win 3.1 and 3.11 were GUIs for DOS. They allowed he user to perform the tasks found in DOS, without using the command line driven interface. With the introduction of Win95, the user now had a more natural GUI, by which to do his/her tasks. Also, Win95 was a stand-alone OS, meaning that the user did not have to install DOS before installing the GUI. Win95 performed all of the functions needed without having to use an underlying DOS text commands.

Windows 3.1 is simple from both the operational and architectural views. This leads to many problems. Here is a list of shortcomings found with Win3.1:
ü All drivers for the base system are loaded in DOS, not Windows. Problems may arise because of the way Windows uses them.
ü Win 3.1’s multitasking is cooperative, which can mean that if one application crashes, the whole system can crash.
ü The GDI heap (application heap), which windows uses for running applications from within windows is limited to 64 KB. If this file grows to beyond that small size, windows run out of memory! The application heap is a 64KB block of RAM, which win 3.1 uses to control the operation of running applications. FACT: many of today’s applications need more than 64KB of space, So Win 3.1 would not be able to even to load them.
ü Win 3.1 runs in a 16 bit environment, which is a slower and less efficient environment than 32 bit. FACT: most of today’s applications are made for the 32 bit environment.
ü There is no native crash protection built into win 3.1
Q-Summary of Win
95
Windows 95 is far more complex than DOS or Win3.1, making it better able to handle today’s more complex applications and hardware.
Here is a list of improvements found with Win95:
q All drivers load within Windows, making them more tightly integrated with the system as a whole.
q Win 95’s multitasking is pre-emptive, which means that if one application crashes or stops responding, then Windows does not crash, but can close or exit that one application. So here Windows controls the show, not the application.
q When an application stops responding to the system, it can be closed by pressing Ctrl + Alt+ Del, then by clicking on “End Task” for that application. See the insert.
q The application heap found in Windows 95 is drastically larger than the one found in Win 3.1.
q Filenames can be as long as 255 characters and can include spaces.
q Plug and Play Technology allows the system to monitor all devices and configure them from within windows to eliminate conflicts.
q Supports pre-emptive multitasking.
q Uses icons, which the user can make into short-cuts to applications by simply right-clicking on the desktop and selecting “NEW.”
q 32-bit operation system
q Organizes programs and data into folders and not directories, subdirectories, or groups.
q Allows the user many more options with the use of the “right click.” Here a user only needs to right click on an object to see a large list of options, see insert.
